        <parameter name="runAs" value="grid"></parameter>
        <parameter name="platform" value="mobile"></parameter>
        <parameter name="runOn" value="emulator-5554"></parameter>
        <parameter name="port" value="4726"></parameter>
        <classes>
            <class name="TestCase.Login"/>

Config file to load it:

 @BeforeTest
    public void start() throws IOException {
        Base b= new Base();
        b.loadConfigProp("52039763fe37a3eb");
        b.loadConfigProp("emulator-5554");
        driver=b.getDriver();
